CAR-TRUCK FRAME.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed 'May 2, 1918. Serial No. 232,024.

To all whom t may concern:

Be it known that I, EDWARD C. LONG, a citizen of the United States, and a resident of Vlestmont borough, county ol Cambria, and State ot Pennsylvania, (whose postotlice address isJohnstown, Pennsylvania,) have invented certain new and useful lmprovements in Car-Truck Frames; and I do hereby declare the Afollowing to be a full, clear, and exact description oit the 'inven tion, such as will enable others skilled in the art to which it appertains to make and use the same. n

My invention relates to car trucks and particularly to the arrangement and construction o1 the side frames of those adapted lior use With freight or passenger cars.

My car truck frame consists essentially of a truss-like structure having an upper member corresponding with the upper chord and a lower member corresponding with the lower chord; diagonal members uniting the two and acting principally in tension; end members adapted to serve as pedestals or supports on the journal boxes and upright members serving also as column guides. My car truck lrameis also provided with a spring-seat, bolster guides, pedestal tiebars and connections for the same.

One o't' the essential features ot' my construction resides in the fact that the main structural member ol my car truck 'trame is composed o't one piece ot 'rolled steel which may first be Atermed of section some what resembling an I-beam but with the 'flanges on one side preferably shorter than those on the other. The intermediate portion ot' said I-beam is split or divided through the web longitudinally thereof and substantially at right angles to the tlanges, thus making two channel sections. The intermediate portions are then spread or spaced apart, truck column guides applied and secured by riveting or bolting, thus forming the truss structure ot my it'ra'me. This construction makes a frame, the principal portions ot which 'are formed entirely ot one piece ol metal, integral at their end portions, split and separated at their inter mediate portions to provide a greater depth and also room for the reception ot the springs and the end o't' the body bolster resting thereon.

Having thus given a general description of my invention, I will now, in order to make the same more clear, re'ter to the one sheet of drawings aceomlmnying and forming part ol this specitication, and in which like ligures. refer to like parts Figure l is a side elevation oli a car truck lrame embodying my invention;

Fig. 2 is a top plan view;

Fig. 3 is a side elevation o't' the bar from which the main members are formed;

Fig. lis a vertical transverse sectional elevation taken on the line IV-V ol Fig. l;

Fig. is a vertical transverse section oft the bar taken on the line V-V of Fig. 3;

Fig. (3 is an end elevation of my improved truck side frame;

F ig. 7 is a cross section ot a modified Yform of bar which I may use;

Fig'. S is a top plan view oitI one oil the truck columns; and

Fig. t) is a transverse section o t the lower arch bar taken ou the line YITX-1X of Fig. l. YReferring now to the characters ot` reference on the drawings .l is the car truck l'rame as a whole, 2 is the space or opening between the upper and lower members, 3 are the flanges ot' the upper arch bar, 4 is the web thereo'l, 5 are, the bevelwl or cut-away ends of the flanges 3, this formation being lor the sake of lightnessl and appearance, (3 is the web portion oft the lower arch bar, 7 are the downwardly projecting flanges thereof, 8 are the inclined members, S) being the bent portions of the [langes thereo'li, as illustrated. 10 are the end portions or journal box bearings which are integral, Vl'l are holes through the thick web oli the end portions adapted to receive the usual journal box bolts, 12 are the truck columns, shown as ol channel or trough section with the ends oit the webs cut away to adapt them lo tit around the upper and lower arch bars. as shown. 13 are the column guides which are con'iposedr ot flat plates riveted by countersunk rivets to the webs olE the truck columns l2, llt a plate bent into trough sha pe to 'form a spring scat and riveted to the lower arch bar and the column guides as shown, this being provided with a filler plate Yl5 secured thereto to lorm a portion o'lt the springseat, the spring plank being composed oiE angles 1,6 riveted to the trame as shown. 17 are the pedestal tie brackets to which the pedestal tie bars '17S are secured. 19 indicates the cross section oit a rolled steel bar ot approximately I-beam shape, trom which the main members are formed, as above described,

this bar, in forming, being split longitudinally of the web at its intermediate portions, leaving the ends integral and the split channel-shaped portions spread apart to the form illustrated. As illustrated in Fig. 7 20 is a modified form of bar or beam from which my main members may be formed, this being provided with grooves 21 to facilitate the splitting thereof. This bar may be split by sawing, slotting, shearing or any other way that may be suitable and the portions may preferably be heated before being shaped into their final form.

It should further be noted that the portions 9 and l0 are formed integrally by bending the edges of the'flanges inwardly,

- thereby forming a tapering section of the inclined member 8 and forming substantial bearing surfaces 10, as illustrated, which comprise the seats which are adapted to rest upon the journal boxes, not shown.

By reason of my construction and arrangement, a very simple frame is provided,

- the main members of which are formed of one piece and, including the column guides, the entire main trussed frame is composed of only three pieces.

Although I have described and illustrated my invention in considerable detail, I do not wish to be limited to the exact and specific details thereof as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are Yembraced within the scope of my invention, or as pointed out in the claims.

I-Iaving thus described my invention, what I claim and desire to secure by Letters Patn ent is 1. In a truck frame, upper and lower arch bars of channel section with their flanges projecting outwardly and the webs intej grally united at their end portions.

l Copies of this patent may be obtained for 2. In a truck frame, upper and lower arch bars of channel section with their flanges projecting outwardly, inclined members connecting the same, the webs being integrally united at their end portions.

3. A truck frame comprising an upper arch bar of channel section with flanges projecting upwardly, a lower arch bar of channel. section with flanges projectingdownwardly, inclined members connecting the same, integrally united at their end portions. Y

4. In a truck frame, upper and lower arch bars of channel section, the webs of which 'are integral at their end portions, the flanges of the end portions being turned inwardly forming bearings.

5. A truck frame comprising upper and lower arch bars and inclined members connecting the same, all of channel section, the webs of which are integral at their end portions, the lower portions of the flanges of the end and side members being turned inwardly.

k6. A truck frame comprising upper and lower arch bars of channel section with their flanges projecting upwardly and downwardly respectively and integrally united `at their end portions, column guides formed of channel or trough section with the end portions of their webs cut away, adapted to fit Y against said upper and lower arch bars, the

flanges of said column guides being secured to the flanges of the arch bars. l

7. In a truck frame provided with upper and lower arch bars, a column member comprising a bent plate of channel form, the

ends of the web portionsof which are cut away and adapted to fit against the lower surface of the upper arch'bar and the upper surface of the lower arch bar, with its flanges overlapping the flanges of said arch bar and secured thereto.

8. A truck frame comprising an upper arch bar of channel section withits flanges' projecting upwardly, a lower arch bar of channel section with its flanges projecting downwardly, an inclined member connecting i the same, the webs being integrally united at their end portions, a pair of column guides, each composed of a bent plate of channel section, the ends of the web of which are cut away and are adjacent to the web portions of the arch bars, the flanges of said Y column guides overlapping and secured to the flanges of the arch bars. l

9. A truck frame comprising an upper arch bar of channel section with its flanges projecting upwardly, anda lower arch bar of channel section with its flanges projecting downwardly, an inclined member connecting the same, the webs being integrally united at their end portions, a pair of column guides, each composed of a bent plate of channel section, the ends of the web of which are cut Vaway and are adjacent'to the web portions of the arch bars, the flanges of said column guides overlapping and secured to the flanges of the arch bars, and bolster guides.
